SHEET-METAL BARREL.

1,394,923, Specification of tet'cers P n Patentcd Oct. 25, 1921.

Application filed .Tune 4, 1920. Serial No. 386,554.

T 0 all whom it may concern Be it known that I, JAMns W. MoNniL, a subject of the King of Great Britain, and resident of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Sheet Metal Barrels, of which the following is a specification.

This invention has relation to that type of barrel represented by my former Patent No. 1,262,222, dated April 9, 1918, in which the body of the barrel is made of a single sheet of metal provided with inwardly extending integral ribs at spaced intervals, these ribs running from head to head of the barrel and increasing in depth toward each head. The objection to this type of barrel is that the increase in the width of the ribs toward the ends of the barrel not only unduly obstructs the interior of the reduced ends of the barrel, but materially reduces the capacity of the barrel, particularly when used as a container for bulky articles. It is one of the objects of this invention to avoid this objection by so cutting the blank that when curled into bilged-barrel form the interior of the ribs may be made of uniform length throughout, as more fully hereinafter set forth.

A further object of the invention is to provide improved means for removably lock? ing the heads within the chime portions of the barrel-body, this locking means being so constructed that the heads are not only locked in place without the use of extraneous fastening devices but may be repeatedly removed and reinserted without materially in j uring either the heads or the chime portions of the barrel, as more fully hereinafter set forth.

In the accompanying drawings:

Figs. 10 and 11 detail horizontal sections taken respectively through the divided and integral portions of the internal rib-like reinforcements of the body; and

Fig. 12 a detail view showing adjacent divided and integral portions of one of the reinforcing ribs.

. The barrel body is preferably formed from a single blank 1 of sheet steel or other suitable metal having portions thereof along opposite edges of the blank cut away, as shown in Fig. 5, to produce chime-forming portions 2. In order to give the body the external appearance of a barrel formed of independent staves and to produce internal rib-like reinforcements, the blank is folded in one direction along straight lines of fold 3 and in the opposite direction along curved lines of fold l and 5 at opposite sides of each line 3. The lines 4 and 5, as shown in Fig. 5, are spaced equal distances from line 3 midway the notched edges of the blank and gradually recede from line B and from each other toward the notched edges of the blank to points coincident with the inner ends of the side edges of the chime portions 2.

vThe excess metal between each two adjacent lines of fold 4 and 5 forms an integral stave connecting web which increases in width toward each notched edge of the blank, and it will be obvious that if the lines of fold 3 extended from end to end of these webs, the webs would form ribs increasing in depth toward each endof the barrel when the blank was folded. Such ribs would unduly obstruct; the interior of the reduced edges of the blank. These lines of cut terminate at the outer ends of the lines of fold 3 and criss-cross back and forth across the longitudinal center of the stave-connecting webs, or in other words, across prolongations of the lines 3, so as to form when the blank is folded pairs of abutting flanges or divided rib walls 7. The flanges 7 form extensions of the two walls of the integral doublewalled ribs 8 formed by folding the undivided portions of the excess metal along lines 3, 4: and 5. It will be observed that the transversely extending portions of the lines of cut v6 decrease in length toward the inner ends of the lines 6 and thus form a plurality of staggered tongues or lugs 9 on the flanges 7 of gradually decreasing length toward the inner ends of said flanges. It will be observed also that by thus forming cuts 6 two lines from the end of line 3, each touching the bases of the tongues 9 on one flange, Wlll be parallel with lines 4: and 5, respectively, so that the body portions of the flanges are of uniform depth from end to end andalso the same depth as the walls of ribs 8, so that the integral and split portions of the riblike reinforcements are of uniform depth from one chime to the other of the completed barrel body.

After the body blank is folded along lines 3, 1 and 5 to produce a bilged body, the meeting ends of the blank are welded or otherwise secured together and the lugs 9 on each flange 7 are bent around the inner edge of the adjacent flange to securely lock the flanges together. In stamping out the notches to form the chime portions 2, 1 also cut away the adjacent end edges of body portions of the flanges 7 so that the outer end edges of the rib-like reinforcements will form inclined head-supporting shoulders or abutments, as more clearly shown in Figs. 7, 8 and 9. The two heads are of similar construction and are secured in place in the same manner. Each head is stamped or otherwise formed from sheet metal and comprises a disk-like body 10 having an upstanding annular flange 11 at its outer edge, which flange 'is pressed inwardly at 12 to form an outwardly facing circumferential channel. The chime-forming portions 2 of the blank are bent outwardly along the lines 13 so that they will form a continuous annular chime concentric with the longitudinal axis of the barrel when the body blank is folded as above described and the cupped heads are inserted in the chimes thus formed. The disk-like bodies 10 of the heads are indented at intervals around flanges 11 by means of a suitable beveled tool or chisel to form, indentations 14: having inclined walls seated against the inclined ends of the flanges 7; A pair of metallic end hoops 15 embrace the chimes and have flaring portions which lie against the bilged surface of the barrel body and are welded thereto. The heads are interlocked with the chime portions 2 by indenting hoops 15 and the chime portions with a suitable chisel or punch at intervals as shown at 16, thereby forcing a part of the metal of the chime portions' into channel 12 on the head flange. The heads may be removed by hammering the inner wall of channel 12 opposite the indentations 16 to flatten out the interlocked portions of flange 11, chime 2 and hoop 15. A pair of hoops 17 are welded to the exterior of the barrel body, said hoops being preferably located so as to span the points of junction of the inner ends of the flanges 7 or split rib portions with the outer ends of the undivided rib portions 8.

It will be obvious that a barrel having a more accentuated bilge than that shown in Fig. 1 may be produced without increasing the depth of the ribbed reinforcements by increasing the curvature of the lines of fold 4E and 5 and removing all metal between the end portions of each two. lines 4 and 5 from the ends of lines 3 to the adjacentedges of the blank 1 not required to form the flanges 7 and tongues 9, shown for example in Fig. 5. The tongues 9 on flanges 7 of such a barrel may be formed of uniform len th, preferably approximating the width of the body portions of flanges 7 which are substantially the same width from end to end as the distance between line 3 and lines 4 and 5 at the central portion of the barrel body, as shown in Fig. 5".v lVhi'le, the chime portions 2, tongues 9 and flanges 7 of this modified form of barrel may be formed, and the necessary amount of surplus metal be removed, invarious ways, I prefer to form the parts 2, 7 and 9 and remove the surplus metal at a single operation. This may be done by stamping out irregularly shaped portions of the blank 1 at intervals along' opposite side edges thereof, one edge of each or wluch portions is defined by the edge of the blank, and the remaining two edges of which are irregular and converge at the end of the adjacent line of fold 3, as shown in Fig. 5. a 7 What I claim is:
